WASHINGTON (AP) - The Supreme Court ruled Thursday that Microsoft Corp. must pay a $290 million judgment awarded to a small Toronto software company for infringing on one of its patents inside its popular Microsoft Word program.
The high court unanimously refused to throw out the judgment against the world’s largest software maker.
Toronto-based i4i sued Microsoft in 2007, saying it owned the technology behind a tool used in Microsoft Word. The technology in question gave Word 2003 and Word 2007 users an improved way to edit XML, which is computer code that tells the program how to interpret and display a document’s contents.
The lower courts say Redmond, Wash.-based Microsoft willfully infringed on the patent, and ordered the world’s largest software maker to pay i4i $290 million and stop selling versions of Word containing the infringing technology.
Microsoft wanted the multimillion dollar judgment against it erased because it claims a judge used the wrong standard in instructing the jury that came up with the award.
The software company said a jury should determine a patent’s validity by a “preponderance” of the evidence instead of the more heightened “clear and convincing” evidence standard instructed by the judge.
The Supreme Court said the “clear and convincing” standard was the correct one.
Justice Sonia Sotomayor, who wrote the court’s opinion, said the courts have interpreted the law the same way for 30 years. During this period, Congress has often amended the patent law, she said.
“Not once, so far as we (and Microsoft) are aware, has it even considered a proposal to lower the standard of proof,” Sotomayor said.
Microsoft now sells versions of Word that do not contain the technology in question.
Chief Justice John Roberts did not take part in the consideration or judgment in this case because he owns Microsoft Corp. stock.
The case is Microsoft Corp. v. i4i Limited Partnership, 10-290.
